Smartphone Call Handling Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smartphone users face challenges in managing calls, particularly in settings where they do not wish to be disturbed, such as meetings or crowded locations, and existing technologies do not effectively differentiate between urgent and non-urgent calls.
Innovation Solution
Implementing a system that allows smartphones to switch between normal and meeting modes, where in meeting mode, incoming calls are assessed for urgency, and callers can indicate if the call is urgent, allowing the user to choose whether to answer immediately or divert the call to voicemail, with adjustable settings for urgency overrides based on user-defined lists.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the smartphone immediately prompts the user to take action with respect to a received call, then the user can respond to all calls promptly, but the user experiences disruptions in settings like meetings or crowded locations
Solution Approach 1:
The system applies different call handling behaviors to different callers based on their urgency status. Important callers receive immediate notification and can override the Do Not Disturb mode, while non-important callers are diverted to voicemail. This local differentiation resolves the contradiction by allowing selective responsiveness without universal disruption.
Solution Approach 2:
The system pre-classifies callers into important and non-important categories before the call arrives. This preliminary classification enables the system to automatically route calls appropriately without requiring user intervention during the call moment, thus maintaining reliability for important calls while preventing disturbances from non-important ones.
2Object-affected harmful factors
If the smartphone diverts all incoming calls to voicemail during Do Not Disturb mode, then disruptions are minimized, but urgent communications from important callers are missed
Solution Approach 1:
The system treats different callers differently based on their importance status. Important callers are excluded from the automatic voicemail diversion and can still reach the user, while non-important callers are diverted. This selective approach prevents both disturbance and urgent communication loss simultaneously.
Solution Approach 2:
The system introduces an intermediary classification mechanism that assesses caller importance before determining call routing. This intermediary layer prevents direct diversion of all calls, allowing urgent communications to be identified and routed to the user while non-urgent calls are diverted, thus preventing both disturbance and information loss.
3Ease of operation
If the smartphone provides multiple call handling options, then user control over call management is improved, but the device complexity increases
Solution Approach 1:
The system segments callers into distinct categories (important and non-important) with different handling rules. This segmentation simplifies the decision-making process by providing clear, pre-defined options for each segment rather than requiring complex real-time analysis, thus improving ease of operation without excessive complexity.
Solution Approach 2:
The system changes the parameter of caller classification from binary (answer/voicemail) to multi-level (important/non-important with different routing rules). This parameter change enables more nuanced call management control while maintaining systematic complexity through automated classification rather than manual configuration.

AI summary
An electronic device capable of receiving and sending calls is configured with at least two modes. When a call is received by a device in a normal mode, the device displays information and presents selectable options for handling the received call. When the device is in a restricted or meeting mode, the device provides authorized callers with the option of prompting the called party to immediately answer the call or to record a message for later retrieval or take other appropriate action. Settings associated with the normal mode and settings associated with the meeting mode are adjustable.
